Several pundits raised concerns over Martinez’s physique and how he would cope in the Premier League but the 28-year-old impressed in his first season in Manchester, making 45 appearances and helping United win the Carabao Cup. But Martinez has struggled to stay fit since then, missing 65 Premier League games over the past three seasons due to various injury setbacks.

The centre-back enjoyed a consistent run in the team in the second-half of last season but another injury during Argentina’s World Cup final defeat to Spain hampered his preparations for the new campaign.

It is not guaranteed that Manchester United will choose to activate that clause, however, leaving Martinez facing a ‘fight’ to save his Red Devils career. While Old Trafford chiefs rate Martinez highly, talkSPORT say they want him to ‘prove his ability to stay fit’ or risk being sold next summer. {"@context":"https:\/\/schema.org","@type":"VideoObject","name":"Carrick reflects on disappointing start as Man United lose to Hull","contentUrl":"https:\/\/videos.metro.co.uk\/video\/met\/2026\/08\/22\/3200761093652133798\/480x270_MP4_3200761093652133798.mp4","description":"Press conference with Manchester United manager Michael Carrick following their 2-0 loss to Hull City at the MKM Stadium in the Premier League on Saturday.","duration":"T6M44S","height":270,"thumbnailUrl":"https:\/\/i.dailymail.com\/1s\/2026\/08\/22\/16\/110791853-0-image-m-13_1787413415956.jpg","uploadDate":"2026-08-22T16:42:41+0100","width":480} To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Up Next Previous Page Next Page window.addEventListener('metroVideo:relatedVideosCarouselLoaded', function(data) { if (typeof(data.detail) === 'undefined' || typeof(data.detail.carousel) === 'undefined' || typeof(data.detail.carousel.el_) === 'undefined') { return; } var player = data.detail.carousel.el_; var container = player.closest('.metro-video-player'); var placeholder = container.querySelector('.metro-video-player__up-next-placeholder'); if (placeholder) { container.removeChild(placeholder); container.classList.add('metro-video-player--related-videos-loaded'); } }); Wayne Rooney has repeatedly urged Manchester United to sign a new centre-back this summer, while Gary Neville fears Michael Carrick’s options at the back are ‘not good enough’. ‘What that result highlighted is that the Man United defence isn’t good enough,’ Neville said on his Sky Sports podcast after the shock opening defeat to Hull. ‘To be fair the club probably know that, they rebuilt the forward line last summer and rebuilt the midfield this summer with a few signings. ‘I don’t know if they’ve got the money or not but they do need a centre-back, and they do need full-backs. They just do. There’s no other way of putting it really. That was highlighted yesterday.’ Rooney, meanwhile, said on Stick to United: ‘I’d like to see another centre-back, I’d like to see another central midfield player and another centre forward. ‘So I think there’s still a lot of work there to be done, but I think it’s really important that the p
